Poor stress and time management (read as crappy self-care) kill marriages and people. They killed my father at the age of 54. Blood pressure pills, statins, and an aspirin a day might have extended his life. However, my hunch is that medication would have only given dad more days on the planet to take really lousy care of himself. (If you really want to get really stressed - read about General Adaptation Syndrome.)
One of the things my marriage has taught me is that the degree to which I take care of myself has a direct impact on Ron. Some might call it co-dependence. I think it’s reality. When being truly present in my marriage stops being one of my multiple tasks, I put Ron, my marriage, and myself in jeopardy. If you want your relationship to work better, you better know when to stop working.
